This paper presents a detailed study of the rotor asymmetry, caused by broken bars, and their effects on the stator current of an induction machine under different supply conditions. The analytical models dedicated to the rotor faults are often penalized by simplifying assumptions, particularly the distribution of the magnetic flux density in the air-gap. The important information is likely to be...
Based on the multi-loop method, this paper analyzes and calculates the stator current, rotating torque and rotating speed of the induction machine, and the main work focuses on the fluctuating components of the torque and the speed caused by rotor winding faults. The conclusions of the analysis are as the follows: the rotor winding faults will cause stator current, electromagnetic torque and rotating...
